Answer:

$7000

Step-by-step explanation:

1. Approach

To solve this problem, one must first find the amount of interest paid in (1) year, then set up a proportion to find out the amount of money that was taken out in the loan. It is given that the interest rate is (4%), and the interest paid after (3) years is ($840).

2.Find the amount paid in 1 year

First, one must find the interest paid in (1) year, this can be done by dividing the interest paid in (3) years by (3).

840 ÷ 3 = 280

3.Find the original amount in the loan

Now set up the proportion, remember, the general format for a proportion is the following,

[tex]\frac{part}{whole}=\frac{percent}{100}[/tex]

Substitute in the given parameters,

[tex]\frac{intereset}{loan}=\frac{rate}{100}[/tex]

Substitute in the values of the parameters,

[tex]\frac{280}{loan}=\frac{4}{100}[/tex]

Cross products,

[tex]28000=4(loan)[/tex]

Inverse operations,

[tex]7000=loan[/tex]

Answer:

x = -8

Step-by-step explanation:

4x - 3 = 6x + 13

   + 3         + 3

    4x = 6x + 16

   -6x   -6x

   -2x = 16

-2 / -2x = 16 / -2

(b) 12y+4h

(c) 2g+10a

(d) 15m+10p

(e) 10e+4

(f) 12+5a

Step-by-step explanation:

Don't be intimidated by the "letter" variables. It is really just simple addition and subtraction. Examples:

For Q1=

y + y + y + y = 4y because there are 4 y's, and since we don't know the values of the y, this is the farthest we can simplify it.

For Q2=

4u - 6u = -2u. Since these two numbers have the same variable, this is just a simple subtraction problem. 4 - 6 = -2.

For Q3=

3a + 2b + 4a + b = 7a + 3b.

Look for the numbers with the same variable. 3a and 4a both have a's, so we add the two and get 7a. 2b and b (b is the same thing as 1b) both have b's, so we add them and would get 3b.

Therefore, the answer is 7a + 3b.

Step-by-step explanation:

add all numbers up then divide by  how many numbers there are.

Answer:

To find the number of three-digit numbers that can be formed using the digits 1, 2, 3, 4, 5, and 6, with repetition allowed, we can use the formula for permutations:

Step-by-step explanation:

Number of permutations = (number of choices for the first digit) x (number of choices for the second digit) x (number of choices for the third digit)

In this case, we have 6 choices for each digit, since we are allowed to repeat the digits. Using the formula, we get:

Number of permutations = 6 x 6 x 6 = 216

Therefore, there are a total of 216 three-digit numbers that can be formed using the digits 1, 2, 3, 4, 5, and 6, with repetition allowed.

However, not all of these will be even. For a number to be even, the last digit must be even, so the last digit can only be 2, 4, or 6. This means that there are 3 choices for the last digit.

Therefore, the total number of even 3-digit numbers that can be formed using the digits 1, 2, 3, 4, 5, and 6 is 366=108.

A right triangle is formed by the provided sides 6 cm, 10 cm, and 8 cm

Given that a triangle has sides measuring 6 cm, 10 cm, and 8 cm.

The question is whether a right triangle is formed by the specified sides.

The Pythagorean theorem states that the sum of the squares of the base and height is equal to the square of the hypotenuse.

Hypothesis 2 Equals Base 2 plus (Altitude)2

Make the hypotenuse 10 cm long.

Specify 6 cm for the base and 8 cm for the perpendicular.

(Hypotenuse)2 LHS (Hypotenuse)

RHS: (Base)2 + (Altitude)2 (Base)2 + (Altitude)2 = (6)2 + 2 = (10)2 = 100 (8)

LHS = RHS: 2 = 36 + 64 = 100

The sides provided meet the requirements for a right triangle.

As a result, a right triangle is formed by the provided sides.

Answer:

Step-by-step explanation:

Given that Angie can mow her lawn 4 times using 1/3 gallon of gas, you want to know how much gas is required for each mowing, and how many times Angie can mow on one gallon of gas.

To find the number of gallons required for each mowing of the lawn, divide the number of gallons by the number of mowings:

  (1/3 gal)/(4 mowings) = 1/(3·4) gal/mowing = 1/12 gal/mowing

It takes 1/12 gallon to mow the lawn once.

The reciprocal of this value has the reciprocal units.

  1/(1/12 gal/mowing) = 12 mowings/gal

Angie can mow the lawn 12 times with one gallon of gas.

Viewing the given triangle, the information given helped to determine side UY to be 90

This is a term used in geometry to mean that the respective sides of the triangles are proportional and the corresponding angles of the triangles are congruent

Hence assuming the corresponding angles of the triangle are congruent then the side should be in proportions

Examining the figure shows that pair of equivalent sides are

WX and WY, XV and YU

The solution is worked out using sides WX and XV, WY and YU

WX / WY = XV / YU

WX / WY = 1/2 since it is a mid segment

1 / 2 = (20p - 95) / (13p - 1)

13p - 1 = 2 * (20p - 95)

13p - 1 = 40p - 190

190 - 1 = 40p - 13p

189 = 27p

p = 7

solving for UY

= 13p - 1

= 13 * 7 - 1

= 90

Answer:

266

Step-by-step explanation:

En Matemáticas, al realizar la operación de División, la regla es la siguiente:

Dividendo ÷ Divisor = Cociente

En la pregunta anterior, se nos da:

Divisor = 19

Cociente = 14

Dividendo =?

Para encontrar el dividendo,

Dividendo = Divisor × Cociente

Por eso,

Dividendo = 19 × 14

= 266

Por lo tanto, el Dividendo = 266

The perimeter of the triangle is 23.66 inches

According to the 30-60-90 triangle theorem, the hypotenuse is twice as long as the shorter leg. Additionally, the sides of this particular triangle have a ratio of 1:2: [tex]\sqrt{3}[/tex].

Now in the question

As shown in the diagram, if the shorter leg of the triangle at 30°, 60°, and 90° is extended in the direction of the right angle by an amount equal to itself and connected to the third point, we obtain a triangle that is congruent with the original triangle. It is clear that the combined triangle is an equilateral triangle with equal sides and angles.

The greatest leg, AB, in the picture is therefore twice as long as the shortest leg of the original triangle and equal to base BC.

Therefore according to the question

given that the shorter leg is 5 inches,

hypotenuse = 5*2 = 10 inches.

the longest leg = 5[tex]\sqrt{3}[/tex], and

The perimeter is thus 5 + 10 + 5[tex]\sqrt{3}[/tex] = 15 + 5[tex]\sqrt{3}[/tex] = 23.66 inches

Answer:

Step-by-step explanation:

You want the cost of each item when person A buys 10 granola bars and 6 cups of yogurt for $18, and person B buys 5 granola bars and 4 cups of yogurt for $9.50.

The equations describing the relations can be written ...

  10g +6y = 18 . . . . . . . person A's purchase

  5g +4y = 9.50 . . . . . . person B's purchase

Subtracting half of the first equation from the second, we find ...

  (5g +4y) -1/2(10g +6y) = (9.50) -1/2(18)

  y = 0.50 . . . . . . . . . . simplify

Substituting this into the first equation gives ...

  10g +6(0.50) = 18

  10g = 15 . . . . . . . . . . subtract 3

  g = 1.50 . . . . . . . . . divide by 10

Each granola bar costs $1.50; each cup of yogurt costs $0.50.
